Ma-kombu
The true one, and the yardstick for the rest.
Flavor profile
The strengths are editorial judgments on a scale within the family, not measurements. They can be compared across the dashi ingredients varieties, not directly against another family.
Ma means true, and the name is no accident: ma-kombu from the waters around Hakodate in southern Hokkaido is the variety that came to set the standard for kombu. The leaves are thick and broad, the broth clear and rich with a distinct sweetness of its own, and that sweetness is also why ma-kombu and katsuobushi are the classic pair: sweet meets smoke. The thickness also makes it good to eat, not just to steep.

Background
Facts
- Origin
- the waters around Hakodate in southern Hokkaido, an area also known as donan
- Kinship
- the same species as the other kombu varieties (Saccharina japonica); the name is the harvest area
- Blades
- thick and broad, which is why it is also used for oboro and tororo, that is, shaved kombu
- Broth
- clear, rich and free of off notes, with an elegant sweetness that comes forward against katsuobushi
- Use
- restaurant dashi, noodle broths and hot pots
In the pot
Broth
- Soaking
- 30 minutes to overnight in cold water
- Temperature
- heat toward the boiling point and lift the leaf out before the water boils
- Note
- a thick leaf releases more slowly than a thin one, so ma-kombu gains more from a long cold soak than hidaka does
